How is the engineering design process similar to the scientific method
They both have to do background research, build prototypes to help the problem, and both record and discuss the results.
simulation

biotic factor
living things
How is the engineering design different the scientific method
Scientific method-
State your question
Formulate your hypothesis, identify variable
design process-
Define the problem
Specify requirements
abiotic
